Oceans & Coasts: CTD & Friends
To COMPLETE this quest, visit one or more of the links above then produce a Creative Reflection about the CTD- be sure to explain (what it is, what it does, and how it is collected) AND what you found exciting or interesting. Be sure to include some reasons for your excitement or interest. Be sure to upload to your website!
In the COMMENTS field, describe what kind of Creative Reflection you produced, and how you submitted it to your teacher (Web link, printed copy, etc).

CTD is the abbreviated name for an instrument package that includes sensors for measuring the Conductivity, Temperature and Depth of seawater. This instrument is mounted within a frame called rosette, which holds a several bottles for sampling seawater that allows scientists to control when individual bottles are closed. It is connected to the ship and the scientists monitor the data to look for temperature that identify hydrothermal plumes. Seawater samples are retrieved from the bottles and chemical/biological analyses.
Because volcanoes, hydrothermal vents, and some other deep-sea features cause changes to the physical and chemical properties of seawater, ocean explorers can use CTD measurements to detect evidence of these features.
It is interesting to know how CTD works because it can cast a high resolution data. Scientists can investigate how physical parameters are related, for example, to the observed distribution and variation of organisms that live in the ocean, which helps us further understand the process that happens in aquatic ecosystem. However, only one sampling site can be sampled at one time, and many casts are needed, which are expensive and time consuming. I did further research and found out that the CTD system was developed by Neil Brown, of the Woods Hole Oceanographic Institution.
